SAND-TRA P..

SPECIFICYATION forming part of Letters Patent No. 382,117, dated May 1,1888.

Application filed Ncvember 3, 1857. Serial No. 254.180. (No model.)

To aZZ whom it may concern:

Be it known that I, BENJAMIN F. SMITH, a citizen of the United States,anda resident of Somerville, in the county of Middlesex and State ofMassachusetts, have invented new and useful Improvements in Sand=Traps,of

which the following, taken in connection with the accompanying drawings,is a specifica- In the drawings, (t represents the sand-.

chamber, which is arranged horizontally, as shown, and has connected toits ends the inlet and outlet pipes 12 and c, asshown in Figs. 1 and 2.The pipes b and c are closed at their meeting edges, preferably by meansof an interposed washer or diaphragm, d, which is confined between theinner ends of the pipes b o by means of the screw-threaded sleeve orcoupling 6, that is screwed over the inner ends of the respectivepipes bc, as shown in the drawings, or in any other well-known manner.

I) is an opening or perforation in the top of the inlet-pipe l), bywhich communication is established from said pipe I) to the interiorupper part of the case a, as shown. 0 is a similar opening orperforation in the top of the pipe c, through which the water passesfrom the case a to the outlet-pipe 0.

Between the openings b and c on the respective pipes 72 and c isarranged within the case or chamber a a vertical division-wall, f, thatis soldered or otherwise secured to the interior portion of the case a,as shown in Figs. 1 and 3, and having its lower portion extending alittle below the openings Us, or below the pipes b c, as shown in Figs.1 and 3, so as to permit the water from the inlet pipe b to passdirectly out through the pipe 0 without first being deflected toward thelower portion of the chamber or case a, and there to deposit the sand orimpurities that may be carried with the water from the inletpipe I).

Within the case a, I attach to the outlet-pipe 0, around its opening a,a cup-shaped deflector, 0, made of perforated netting or suitableperforated material, which is preferably open at the top, as shown inthe drawings, and it serves to arrest the sand or heavy particles thatare carried with the water from pipe b, and to deflect the same towardthe bottom of the sand-chamber, as shown in Figs. 1 and 3. I do not,however, wish to confine myself to a perforated deflector 0 made open atthe top, as, if so desired, it may be carried upward, as shown in dottedlines marked 0 in Figs. 1 and 3, and thus still further prevent the sandor other impurities from passing out through the pipe 0 and its openinga.

a is a detachable screw -pl u g screwed through a socket in the lowerportion of the case or sand chamber a, and a is a similar detachablescrew-plug screwed through the top portion of the case a, which plugsare to be removed when it is desired to force out the accumulations inthe lower portion of the case a, as is common in sand=traps for Artesianor driven wells.

I am aware of the Patent No. 280,579, issued to myself, as assignee ofJ. T. Sell, J uly 27, 1880, for improvements in sand'traps, in whichavertical case is used with inlet and outlet pipes, and adeflecting-shield arranged at the junction of said pipes; and Iwish tostate that I do not claim the construction and arrangement as shown anddescribed in the said patent; but

What I wish to secure by Letters Patent, and claim, is-

The horizontal case or chamber at, having inlet and outlet pipes b c,with perforations b c and partition (1, as described, combined with thecase-partition f, secured to the interior of to this speeification,inthe presence of two subcase a, and extending downward below the scribingWitnesses, on this 1st day of Novemperforations b c, and the perforatedor nether, A.
